The company has now scored FDA approval for its Prevnar 20 vaccine for adults 18 and older.
The vaccine is the first to offer protection against 20 serotypes of pneumococcal disease that cause the majority of pneumonia and invasive pneumococcal disease. In addition to the capsular polysaccharide conjugates already included in Prevnar 13, the new vaccine adds conjugates for seven different serotypes linked with invasive pneumococcal disease, antibiotic resistance and meningitis.
